Problem with analog capture on ZR60
on Jul 1, 2003 at 6:17:20 pm

I'm using a Canon ZR60 to pass-thru capture old 8mm analog. My system setup is a P4 2.4GHz, VIA 1394 card, 1 Gig RAM, second 160 Gig 7200 rpm ATA133 (nothing on it yet) on it's own Maxtor (Promise) ATA133 controller.

When I'm pass-thru capturing, I seem to get a frame drop when the analog video source has sudden motion. This usually only happens about every 10-15 minutes. I tried capturing to DV tape first then transferring and this seems to drop frames more often (every 30-40 seconds).

In pass-thru capture, I can cause frame drops by fast forward and rewind of the 8mm analog source.

I'm confused about all of this. I thought that once the A/D in the camcorder was done with the digitizing that the 1394 transfer was independent. What I'm seeing seems like it's content-specific and can cause dropped frames.

By the way, I've transfered original DV source with no problem.
Do I need a different 1394 card or is there a flaw in the camcorder analog capture or something else?

Any help would be appreciated.

Sometimes you can run into problems with dropped frames when you use your digital camera for pass-through. That is why we recommend a dv/analog converter such as Datavideo's DAC-100. Check it out here It's $199.95.
